Yeah I much prefer the way Skyrim levelled up. But the AI in Fallout 3 and 4 did not have swords either. I don’t find the AI worse or better than most other games I have played recently. Unless you have a companion with you and they do stupid things.
Same, i find the AI to be the same or even slightly better tbh. They stay in cover a lot and make you move position to flank them. It's quite dynamic especially when its a large room with multiple levels to so you're not just focusing ahead but need to look up and down to avoid fire.
